This study assessed the importance of diarrhoea-related illnesses among children five years of age or less at the University Hospital, Legon and the importance of packaged water handling in the contamination of drinking water of pre-school children. Diarrhea-related diseases (DRD) accounted for 6.3% of cases involving children five years and below reporting at the University Hospital, Legon during the period of the study. Generally, greater number of cases (DRD) were reported among males (6.9%) than among females (5.6%). High counts above recommended levels of either Total Heterotrophic Bacteria, Pseudomonas or Total Coliforms were observed in 88% of the water samples tested. Inadequate cleaning of water bottles and in some instances the use of inappropriate water bottles (reusing PET mineral water containers) contributed to the poor quality of the drinking water of the preschool children. A greater part of the contamination of the drinking water occurred at home and not at the schools. Parents therefore need to be targeted with water, sanitation and hygiene related health education.","PeriodicalId":117280,"journal":{"name":"Ghana journal of science","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126580997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The animals were divided into four groups of four animals (n = 4). Three groups were implanted with 129 g, 258 g and 387 g of thin plastic bags into the rumen through rumenotomy, while the fourth group was subjected to rumenotomy without implanting plastic bags, and served as control. All the animals were monitored daily for 6 weeks following implantation. Presence of plastic bags in the rumen was characterized by anorexia, severe depression, discomfort, dehydration, firmness and asymmetrical distension of the abdomen, ruminal hypomotility and diarrhoea with intermittent constipation, weight loss, terminal recumbency and death. The severity of these clinical manifestations increased with increased quantities of plastic bags and their duration in the rumen. Sheep implanted with 258 g and 387 g lost 7.8 percent and 14.2 percent of their initial mean body weight, respectively, by the end of 6 weeks. Presence of plastic bags in the rumen could interfere with digestion, with a gradual loss in body weight, productivity and occasional mortality. Plastic bags in the rumen should be considered as a differential diagnosis in sheep presenting the observed clinical signs, especially in urban and periurban areas.","PeriodicalId":117280,"journal":{"name":"Ghana journal of science","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116961637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Densu river basin is characterised by accelerated land degradation. A number of Integrated Water Resources Management (IWRM) interventions have been implemented in the basin. Reports suggest there has been an improvement of physicochemical parameters of the water resources. However, there is no recent study on fluvial sediment transport in the basin. This paper assessed sediment transport into the Weija reservoir via the Densu River. Weekly suspended sediment concentration and river discharge were monitored over a 1 year period to quantify sediment yield into the reservoir. The results indicated that total annual suspended sediment yield, and annual specific suspended sediment yield were 5375 t yr -1 and 2.0 t km -2 yr -1 , respectively. These were relatively low compared to results obtained by past studies on the Densu basin at upstream Mangoase (6146 t yr -1 and 2.49 t km -2 yr -1 ) and other river basins in Ghana. Parameters established from a yield rating curve indicated that parts of the basin were degraded and sediment transport in the basin was largely due to the availability of sediment in the catchment and not just due to high river discharges. The relatively low sediment transport at Weija may be indicative of the success of the IWRM interventions. It is recommended that these be sustained and/or intensified.","PeriodicalId":117280,"journal":{"name":"Ghana journal of science","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116780551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology involved live-trapping of small mammals and recording bird species using ad hoc observations timed transect walks along trails and transects. Fifty individuals of nine species of rodents were recorded, with Mastomys erythroleucus (multimammate mouse) being the most abundant. Small mammal species diversity was highest (H’ = 1.88) and lowest (H’ = 0.98) in Tain II and Tain I forest reserves, respectively. The presence of some savanna species in some of the reserves indicated high levels of degradation. Fifty-four bird species, representing 22 families, were recorded, with 16 of the species being under national conservation protection. It is recommended that the reserves be zoned into smaller management areas to enable more efficient management, through initiation of reforestation programmes, anti-poaching patrols, research, and long-term monitoring. There is the need for intensive education of the local inhabitants on wildlife conservation awareness.","PeriodicalId":117280,"journal":{"name":"Ghana journal of science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129407562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fauna examined were mammals (large and small), birds and reptiles. The sources of information include the Internet, books, journals and faunal survey reports on various forest reserves and protected areas in Ghana. The threat to fauna appears to be highest in the rainforest and the semi-deciduous forest. For mammals, 41.8 and 28 per cent are threatened in the rainforest and semi-deciduous forest, respectively. The comparable figures for birds are 4.5 and 3.1 per cent. The most endangered (critically endangered) mammal species in Ghana is the Miss Waldron’s red colobus monkey (Procolobus badius); current thinking is that it has gone extinct. Six species of mammals are endangered (IUCN) in the semi-deciduous forest, two in the rainforest and four in the inland savanna; no endangered species has been recorded in the coastal scrub and grassland. The main causes of threat to fauna in forest reserves are habitat degradation and fragmentation, to which mining activities have been contributing in recent times.","PeriodicalId":117280,"journal":{"name":"Ghana journal of science","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132220449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
